1

scrotum

the sac that holds the testes

New cards
2

testis (pleural testes)

the organs that make sperm cells

New cards
3

epididymis

the series of hollow tubes that stores mature sperm cells

New cards
4

ductus (vas) deferens

the tubes sperm cells travel through during ejaculation, before the urethra. The sperm cells are suspended in salt water solution.

New cards
5

seminal vesicle

this gland secretes a sticky yellowish/whitish fluid which makes up about 60% of semen. The fluid enters the urethra via the ejaculatory ducts

New cards
6

urethra

transports urine from the bladder the outside of the body, and also transport semen from the reproductive organs to the outside of the body

New cards
7

ejaculatory duct

small paired tubes that carry sperm from the vas deferens and fluid from seminal vesicles into the urethra, they pass through the prostate gland.

New cards
8

bulbourethral gland

during arousal this gland secretes a small amount of slippery fluid into the urethra to neutralize any acidic urine and lubricate the glands

New cards
9

prostate gland

this gland secretes a thin, milky white fluid, which makes up about 30% of semen. This fluid enters the urethra as it passes through the prostate.

New cards
10

penis

made of 3 spongy tissue layers

  • the paired corpora cavernosa

  • single corpus spongiosum

New cards
11

glans of the penis

sometimes called the head, covered by a layer of skin called the foreskin.

New cards
12

bladder

the hollow sac that stores the urine formed in the kidney

New cards
13

spermatic cord

made up from ductus deferens, the testicular artery, and testicular veins. Travels from the testis of the scrotum, through the inguinal canal and into the abdominal cavity

New cards
14

ovary

the organ that makes oocytes (egg cells)

New cards
15

uterine tube

transports ovulated oocytes from the ovary to the uterus

New cards
16

uterus

a hollow structure that contains a thick layer of smooth muscle, and endometrium. Located in the pelvic cavity, but will expand into the abdominal cavity during pregnancy

New cards
17

myometrium

smooth muscle in the uterus

New cards
18

endometrium

tissue lining the smooth muscle in the uterus

New cards
19

fundus

the dome shaped superior aspect of the uterus

New cards
20

cervix

the narrow muscular opening to the uterus containing a sticky mucus to prevent the passage of bacteria and pathogens

New cards
21

broad ligament of the uterus

the “ligament” that is a fold of peritoneum that covers and supports the uterus

New cards
22

vagina

the hollow muscular tube that connects the uterus to the outside world, the external opening the vaginal canal is called the vaginal orifice

New cards
23

urethral opening

the walls of the vaginal canal secrete a fluid that lubricates the canal and orifice during sexual arousal

New cards
24

labia minora

two thin folds of skin that enclose the vaginal orifice and urethral opening

New cards
25

labia majora

two thicker folds of skin that enclose the labia minor and the glans of the clitoris

New cards
26

glans of the clitoris

structure containing a spongy erectile tissue
